Abstract (en)

An organic light emitting device includes a substrate, an anode and a cathode disposed over the substrate; a luminescent layer disposed between the anode and the cathode wherein the luminescent layer includes a host and at least one dopant; the host of the luminescent layer being selected to include a solid organic material comprising a mixture of at least two components wherein the first component of the mixture is an organic compound that is capable of transporting both electrons and holes and that is substantially non-polar; and the second component of the mixture is an organic compound that is more polar than the first component; and the dopant of the luminescent layer being selected to produce light from the light emitting device. <IMAGE>
